4. Related materials: functionalized SWCNT, double, multi walled CNTs, customized dispersion
Single walled carbon nanotubes used in supercapacitor electrode materials:
1. Directly use CNT to do electrode material.
2. Production electrode material with activatedCNT.
Using HNO3, CO2, air and otheractivated CNT, increasing the specific surface area, thereby increasing thespecific capacity and improve the cycle performance.
3. CNT with metal oxide produced electrodematerial.
And transition metal oxide (RuO2,NiO2, MnO2, etc.) complex, when they complex, can occur rapidly reversibleelectrode reaction on the transition oxide electrode, while CNT mesh structurewith large specific surface area and good CNT conductive electron transfer moreinto the interior of the electrode, the energy stored in the three-dimensionalspace, and ultimately to improve the specific capacitance and energy density ofthe electrode.
4. CNT with conductive polymer compositematerials produced electrode material
Put conductive polymer (PPV, PAN, PANI) coatedon the carbon nanotube, etc., so that the two complementary advantages, thecomposite electrode material having superior conductivity of the conductivepolymer and cycle characteristics, and the capacity has also greatly improvedthan carbon nanotubes.
5. CNT with graphene produced electrode material
With the big surface area, high crystallinity,good conductivity of carbon nanotubes, pore size can be controlled by thesynthesis process, which is an ideal electric double layer capacitor electrodematerial. Since carbon nanotubes have an open porous structure, and caninterface with the electrolyte to form an electric double layer, which gathereda large charge, the power density of up to 8000W/kg. Its measured at differentfrequencies respectively capacitance 102F / g (1Hz) and 49F / g (100Hz).
